Question
**Hypothesis Testing Example**

The test statistic of \( z = 1.12 \) is obtained when testing the claim that \( p > 0.3 \).

**Steps:**
1. **Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed.**
2. **Find the P-value.**
3. **Using a significance level of \( \alpha = 0.05 \), determine whether to reject \( H_0 \) or fail to reject \( H_0 \).**

### Solution

a. This is a **right-tailed** test.

b. P-value \( = \_\_\_ \) (Round to three decimal places as needed.)
